A to reduce
B reducing
为什么选B？
为什么不能是to do 结构作目的状语？
请看清楚题目再做答

因为不存在hope sb. to do sth.这类句式，所以只能B
请楼主参考以下内容：

hope意"希望"指能达到或实现的"希望".结构为:
1:hope+to do sth. 例I hope to hear from her.
2:hope+that从句.例I hope that you will have a good time.
3:hope for sth例He hope for more book

wish 表示"希望,愿望",指可以是可能实现的,也可能是难实现的.结构为: 1:wish +to do sth.例I wish to vist the West lake.
2:wish+sb.+to do sth. 例I wish him to stady hard.
3:wish+that从句(用虚拟语气)例I wish I were a bird.
4:wish+sb. +宾补 例I wish you happy.
